# Connecting to Amazon S3 source actions with a source enabled for events
<a name="create-S3-source-events"></a>

The instructions in this section provide the steps for creating the S3 source action that does not require that you create or manage Amazon CloudTrail resources. 

**Important**  
The procedure to create this action without Amazon CloudTrail resources is not available in the console. To use the CLI, see the procedures here or see [Migrate polling pipelines with an S3 source enabled for events](update-change-detection.md#update-change-detection-S3-event).

For a pipeline with an Amazon S3 source, modify the pipeline so that change detection is automated through EventBridge and with a source bucket that is enabled for event notifications. This is the recommend method if you are using the CLI or Amazon CloudFormation to migrate your pipeline.

**Note**  
This includes using a bucket that is enabled for event notifications, where you do not need to create a separate CloudTrail trail. If you are using the console, then an event rule and CloudTrail trail are set up for you. For those steps, see [Migrate polling pipelines with an S3 source and CloudTrail trail](update-change-detection.md#update-change-detection-S3).
